A legacy video editor or playback device may accept AVI but not HEIF photos. Converting makes a video clip from the still image; it does not add motion.

What the HEIF format is

HEIF (High Efficiency Image File Format) stores still images, commonly with the .heic extension. iPhones and some other phones create HEIF photos, so the format often appears when transferring camera images to older software or devices.

What the AVI format is

AVI is a video container used by Windows software and older playback systems. It can hold video encoded with different codecs, so compatibility depends on both the AVI container and the codec inside it.

How to convert HEIF to AVI

Convert, then download the AVI file or files.

Offline with desktop software

FFmpeg is free and runs on Windows, macOS, and Linux. Use a build that can decode HEIF. This command makes a five-second, 30-fps AVI from one HEIF image, using the MPEG-4 Part 2 video codec:

ffmpeg -loop 1 -framerate 30 -i input.heic -t 5 -c:v mpeg4 -q:v 3 -pix_fmt yuv420p output.avi

Replace input.heic with the source filename and change -t 5 to set the clip duration in seconds. The command creates a silent video.

Quality and limitations

A still photo becomes repeated video frames, not an animated image. AVI is a container rather than a single codec standard; MPEG-4 Part 2 is the codec used above, but a target device may require a different codec. Re-encoding can reduce image quality, and converting cannot restore detail lost in the original HEIF.
